Change default editor
There is a quick way to change your default editor, whichever you want.
First open up a terminal by going to Applications > Accessories > Terminal (in Ubuntu) or press Alt + F2 and type in terminal. Now that you have a terminal open, let’s get down to viewing your history.
Open up .bashrc by typing:
vim ~/.bashrc
Now to change your bash default editor find.
export EDITOR
However, if you can’t find that, just add this to the top.
export EDITOR=vim
Personally I like vim. You can use pico (/usr/bin/pico), nano (/usr/bin/nano), or any other editor you like.
Like always, you can learn more about this by doing the following:
man bash
